Hi, I'm new to both PostgreSQL and web-based application development; I read the FAQ at postgresql.org (perhaps this discussion group has another FAQ that I haven't found yet?) and didn't see this addressed. I'm creating a table with a column of type text, to be used in a php web application, where I'll be accepting user input for that text field. Are there characters, maybe non-printing characters, or perhaps even whole phrases, that could cause problems in my database or application if I were to allow users to enter them into that column? If so, does anyone happen to have a regular expression handy that you think is a good choice for text columns' CHECK constraint? Or maybe a link to a discussion of this topic?
